Determining granularity
One key consideration that is often overlooked is determining the granularity of the data that's needed. For example, when working with geographic data, you may have values for continent, region, country, state, city, ZIP code, street, and so on. But if you're only going to report on country data, you may not need all those other dimensions. Or perhaps you are processing order data; you may want to consider whether you need the details for each individual line item in each individual order – maybe your analysis will be fine with just the total order amount per day. In this recipe, we'll look at a quick method to help reveal the data actually in use in a Tableau Desktop visualization.
